Abstract
The utility model discloses a projection welding bottom electrode capable of cleaning surface welding slag of the projection welding bottom electrode automatically. The electrode comprises a bottom electrode with a through hole, a nut positioning pin, a bottom electrode transitional sleeve with a cavity, a compressing gasket and a spring, and further comprises a one-way throttling valve and a compressed air source connected with the one-way throttling valve through a hose. According to the projection welding bottom electrode capable of cleaning surface welding slag of the projection welding bottom electrode automatically provided by the utility model, the one-way throttling valve is installed on the side face of the bottom electrode transitional sleeve, and compressed air can enter into the bottom electrode transitional sleeve through the throttling valve, so that the surface welding slag of the bottom electrode can be automatically cleaned, and the projection welding nut welding quality is effectively guaranteed.
Description
Technical field
The utility model relates to welding equipment, relates in particular to a kind of projection welding bottom electrode of its surperficial welding slag of energy Automatic clearance.
Background technology
Nut projection welding technique is very extensive in auto manufacturing's application at present, and project-welding nut is as fastening automobile class safety member, and the projection welding quality directly affects user's personal safety.
Welding slag is difficult to avoid in nut projection welding technique at present, traditional method for cleaning is by operative employee's visual inspection projection welding bottom electrode surface, there is lower electrode surface to have welding slag as finding, then ends welding job, continue again weld job behind the welding slag of clearance by hand surface.
The pattern of above-mentioned this cleaning welding slag, being affected by human factors frequent appearance lost efficacy, in case lower electrode surface is residual welding slag is arranged, project-welding nut intensity will greatly descend even the rosin joint phenomenon occur, therefore seek a kind of method that can the Automatic clearance welding slag from projection welding equipment, reduce human factor to the impact of projection welding quality, become the technique bottleneck that nut projection welding technique is badly in need of solution.
Summary of the invention
The purpose of this utility model, provide in order to address the above problem exactly a kind of Simple And Practical, can its surperficial welding slag of Automatic clearance projection welding bottom electrode.
The purpose of this utility model is achieved in that
The projection welding bottom electrode of a kind of its surperficial welding slag of energy Automatic clearance of the present utility model, comprise the bottom electrode with through hole, the nut alignment pin, bottom electrode with inner chamber excessively overlaps, clamping pad and spring, described spring is located in the inner chamber of described bottom electrode spacer shell, the bottom of described clamping pad is located in the inner ring of described spring upper end, described bottom electrode is fixed on the upper end of bottom electrode spacer shell with thread connecting mode, the through hole of described bottom electrode is passed in the lower end of described nut alignment pin, and contact with described clamping pad, described projection welding bottom electrode also comprises one-way throttle valve and is connected the compressed air source that connects by flexible pipe, described one-way throttle valve is fixed in an excessively side of cover of described bottom electrode, and is communicated with the inner chamber of the excessive cover of this bottom electrode.
The utility model is installed an one-way throttle valve in its bottom electrode spacer shell side, and compressed air can enter in the bottom electrode spacer shell by this choke valve, realizes the purpose of Automatic clearance lower electrode surface welding slag, has effectively guaranteed convex welding nut welding quality.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
See also Fig. 1, there is shown the utility model projection welding bottom electrode, this projection welding bottom electrode comprises the bottom electrode 1 with through hole 11, nut alignment pin 5, bottom electrode with inner chamber 21 excessively overlaps 2, clamping pad 4, spring 3, one-way throttle valve 6 and compressed air source 7, spring 3 is located in the inner chamber 21 of bottom electrode spacer shell 2, the bottom of clamping pad 4 is located in the inner ring of spring 3 upper ends, bottom electrode 1 is fixed on the upper end of bottom electrode spacer shell 2 with thread connecting mode, the through hole 11 of bottom electrode 1 is passed in the lower end of nut alignment pin 5, and contact with clamping pad 4, one-way throttle valve 6 is fixed in an excessively side of cover 2 of bottom electrode, and be communicated with the inner chamber 21 of the excessive cover 2 of this bottom electrode, one-way throttle valve 6 is connected by flexible pipe 8 with compressed air source 7.
Operation principle: when the operative employee steps on the device start switch, the descending precompressed nut of top electrode, until nut with after surface of the work contacts fully, the energising welding, after welding is finished, top electrode begins up, meanwhile, start working with compressed air source 7, compressed air enters flexible pipe 7, then compressed air enters in the inner chamber 21 of bottom electrode spacer shell 2 through one-way throttle valve 6, owing to have the gap between nut alignment pin 5 and the bottom electrode 1, the compressed air that therefore enters in bottom electrode spacer shell 2 inner chambers 21 can overflow from the gap, thereby the welding slag on bottom electrode 1 surface is blown out bottom electrode 1 surface, when top electrode was up to peak, compressed air source 7 quit work, and this moment, flexible pipe 7 interior non-compressed airs entered.When the operative employee steps on the device start switch again, the equipment above-mentioned action that will circulate.
Above embodiment is only for illustration of the utility model, but not to restriction of the present utility model, person skilled in the relevant technique, in the situation that does not break away from spirit and scope of the present utility model, can also make various conversion or modification, therefore all technical schemes that are equal to also should belong to category of the present utility model, should be limited by each claim.
